Well thats up to you. If you have the money go oem everything if not go wiesco. I was A class mx racer for years and used wiesco just cause comes with everything and do myself is no brainer. I always put new kit in every year keeps it fresh that way 👍 , honesty only had one fail . but im hard on engines

Hello my name is Alex, I'm from Spain, owner of a Yz 250 2007 and seen on many forums that many people have bad luck with wiseco rods, I have to say that my Yz 250 has one installed with 122 hours of use. I am not a professional but I'm going with the Mx circuit two times a week, gave me the Yz 250 with 25 hours of crankshaft, the question is that I want to change the crankshaft, as I said, I have not noticed problems but now I want to change it because the rod is out of tolerance My question is if I trust the cranks of the hounds. or go to the safe and put me in or I don't know what do and misreading both of them thanks in advance I'm sorry my English is a translator

Honestly, OEM cranks are dirt cheap. If it does fail, you can be rest assured it wasn’t the crank or manufacturing defect. Search on eBay for the part # 5UP-11410-10-00. You will get better results than just searching for a YZ250 crank. You can also search that number on Google and see what pops up from parts stores available to you.

Actually I have thought about making a complete engine rebuild then I have seen that kit wrench rabbit with crankshaft hotrods and all bearings and seals that such is this brand? Since the kit is more profitable than all oem

I am not sure about those wrench rabbit kits; I can price out an entirely OEM top and bottom rebuild kit for around $350 or less, but prices could be different over in Spain.

I stay away from wrench rabbit kits. 1 it is over priced, 2 it gives you crappy main bearings, 3 it's better to go OEM.

TT goldmember the kit wrench rabbit I get for $ 720 with the shipping and tariffs etc, I'm sure that OEM will be better but here in Spain only the crankshaft costs € 350 if I wanted to make a kit like wrench rabbit but with OEM it would be about € 1000 about 1238 dollars, that's why I was thinking about the wrench rabbit kit but I'm afraid that crankshaft or bearings will fail

Hey guys, I have a 2003 cr125 I bought a couple weeks ago and I'm having a problem with it. The spark plugs die every about 15 minutes, with hotter plugs it will last about 45 minutes. I herd that if the timing is off it can over heat the plugs and burn out the the resistor. Is there any truth to that? The reason I thinks it's not fouling is because when the plug dies it gives no spark no matter how much you clean it, And it shorts out.

Hi all, First post here. I need some help.
Ive just bought an 05 yz 125 for a good price but it needs some work. One of the forks has some pretty severe pitting of the chrome on the stanchion towards the bottom near the brake caliper mount.
Ive found a pair of good condition forks from an 04 yz250 for a very good price, from the research ive done its seems that both the 04 & 05 forks are 48mm but are different, with the 05 fork regarded as being better than the 04, but not as good as the 06 + sss forks.
Im looking for the cheapest way to get me riding, Will I be able to make the 04 forks work with my 05 triple clamps, brakes, wheel, axle, spacers etc? If not does anyone know what hardware id need to make it work?
Finally, as a last resort, does anyone know if i could swap the stanchion from the 04 fork into my 05 forks?
Thanks, Andrew

I bought a 2006 YZ250, have ridden it 5 times. It needs some tuning, but I am not sure I'm keeping it so don't want to spend much on it.
Has fmf gnarly expansion chamber and turbine core silencer.
I ride about 1000 feet above sea level.
I'm going to clean the carb and check the jetting. What is a good jetting for me? 85 main jet?
Also check the reeds. Is there a big difference between getting aftermarket reed cage and reeds or just getting a cheap aftermarket set of reeds that fit the stock cage ie. Boyesen Power Reeds?
The other things I'm going to do is permatex all the joints in the exhaust system and a compression test. It was 220psi 5 rides ago so I'm guessing itll be fine. Its bogging a bit but I'm thinking its carb and definitely exhaust joint related.
Let me know if I'm overlooking anything that could make the bike run crisper and more bottom end without throwing much money on parts

A tiny clear rubber tube on bottom of carb. On bottom sort of on side, by floats, the other end just hanging down. Was it always like this? Or does the other end go somewhere? Today after multiple trys with kick, choke on/off ,,,fuel keeps pouring out the tube. This bike has always been hard to start. Thanx guys!
